Subtracts one value from another and pushes the result onto the evaluation stack.

public static readonly System.Reflection.Emit.OpCode Sub;

Field Value

OpCode

Remarks

The following table lists the instruction's hexadecimal and Microsoft Intermediate Language (MSIL) assembly format, along with a brief reference summary:

Format Assembly Format Description
59 sub Subtracts one value from another, returning a new numeric value.

The stack transitional behavior, in sequential order, is:

  1. value1 is pushed onto the stack.

  2. value2 is pushed onto the stack.

  3. value2 and value1 are popped from the stack; value2 is subtracted from value1.

  4. The result is pushed onto the stack.

Overflow is not detected for integer operations (for proper overflow handling, see Sub_Ovf).

Integer subtraction wraps, rather than saturates. For example: assuming 8-bit integers, where value1 is set to 0 and value2 is set to 1, the "wrapped" result will be 255.

Floating-point overflow returns +inf (PositiveInfinity) or -inf (NegativeInfinity).

The following Emit method overload can use the sub opcode:
